Asus has stayed pretty true to the pure Ice Cream Sandwich system on the Transformer Prime, in fact there are just a few extra widgets for quickly reading your emails, seeing the weather forecast and controlling music tracks, plus a couple of design tweaks to note.

There are no extra app widgets like there are on the Lenovo ThinkPad Tablet for adding favourites to an app wheel or an app launcher.

Frankly, these additions offer a nebulous value beyond the stock operating system, and the intuitive Android interface allows you to easily navigate to the apps you want.

Down in the tool bar at the bottom of the screen you'll find back, home and multitasking buttons – the latter of which opens up the Ice Cream Sandwich multi-tasking menu, allowing you to view all open apps and close the ones you don't want any more by sweeping left or right over the thumbnail.

If you like taking screenshots of your tablet's display, then as well as holding down the power/lock and volume down keys, in the settings menu you can also set the multi-tasking button to take a shot when held down.

In the right corner of the tool bar you'll find the clock, battery and notifications bar – tap on this and it'll open up the notification area, allowing you to get a quick overview of your latest emails and social network updates, as well as toggle settings such as Wi-Fi, Bluetooth and GPS on and off.

There are three additional icons you can use here to set the power level on the Prime - eco mode, balanced and performance, depending on the tasks you're performing and the amount of battery you wish to conserve.

Thanks to that beefy quad-core processor, the Transformer Prime has no trouble running Ice Cream Sandwich, allowing you to glide through the five homescreens and your lists of apps and widgets without any hint of slowdown or lag.

The Asus Transformer Prime can happily run a multitude of applications at the same time without issue, and we didn't experience any slow down even when performing demanding tasks.

There's not too much more to say about the Transformer Prime's interface, because Asus have kept things simple, and more importantly easy to use.

The metallic spun finish on the ultra-slim and light Transformer Prime sets a new benchmark in the art of tablet design. Only 8.3mm thin and 586g light, the Transformer Prime re-defines the rule of the mobile life, making it super easy to carry and transport.

The world's first Quad-core CPU tablet. The most powerful tablet ever.

Powered by the world's first Quad-core processor NVIDIA Tegra 3, the Transformer Prime browses the web and plays 1080p HD video at blazing speeds. The snappier response time and better multi-tasking performance make the Transformer Prime a true mobile entertainment powerhouse.
